This invention relates 'to a lock box and has for its object to provide a box or the like carried on the lid of which is a system of permutation locks.

Another object of the invention is to provide a toy box, cigar box, candy box, tool box, or the like, provided with a very inexpensive permutation lockngmeans. f

A Stm further objecrof the invention is to pre..

vide a box locking meansprovided with a series of independent but cooperating permutation locks.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which:

Figure 1 is a top plan View of a box embracing my invention,

Figure 2 is a similar view, the box top being shown wide open,

Figure 3 is a section on line 3-3, of Figure 1,

Figure 4 is a detail plan View of a symbol carrying disk and Figure 5 is a similar view of the reverse side of Figure 4.

In the following specification and in the several views in the accompanying drawings I0 indicates my invention which comprises a series of permutation locks II, I2 and I3, attached to the hinged top I4 of abox I5.

As all three of the locks are identically constructed it will be necessary here to describe one in detail. Lock Il, for instance, includes an 0perating knob I6, seating on a spacer disk I1, and to which is fixed a shaft I8, projecting through a bore I9 in the top I4. Mounted on the shaft I8 is a series of disks 20, 2|, 22, 23. The disk I1 is fixed to the top I4. The disk 20 is fixed to the shaft I8, to turn therewith. The disks 2| and 23 are xed spacer and friction disks and the disk 22 seated between said disks 2| and 23 is the tumbler disk 22 and which is of greater diameter than the spacer disks and of approximately the same diameter as that of disk 20, which is a dial disk. The disk 22 is provided with a V-shaped cut-out 24 in its peripheral portion 25. All of said disks are held secure upon the shaft I8, by a washer 26. held in place by a pin 21.

The disk or tumbler 22 while being frictionally held in place to rotate with shaft I8 by the disks 2| and 23 yet may be manually rotated upon the shaft for the purpose presently to be explained.

The dial disk 20 has placed around its peripheral edge on both sides thereof a series of symbols 28 and 29 respectively, a single one of which is adapted to be made to align with a bore 30 in the box .top I4. As there are three of the locks there projecting into which are the shanks 34 and 35 of v tumbler engaging members 36 and 31, which are in the form of heads on said Shanks and which heads stand far enoughy above the top surface 38 of Wall 33 to permit the periphery of the disk 22 to pass between saidtop surface and said head 31 whereby the disk.22, secures said top I4, from being opened. It is to be noted that thev tumbler disks of both locks I2 and I3 are so located on opposite sides of wall 33 as to engage under the member 36, while the tumbler disk 22 of lock I I is' engageable by the member 31.

The symbols 28 and 29 on the reverse sides of the dial disk 20 are so arranged that when certain chosen symbols appear in the openings 3D, 3| and 32 of the box top, the same symbols will appear between the V-shaped notches 24, 24a and 24h on the underside 39 of the top. Therefore, in order to set the dials to open on a predetermined set of symbols, the box top is thrown back and the disk 22 of each lock is rotated by holding secure to the knobs I6 thereof and manually moving said dial 22 against the action of the friction disks until the desired symbols appear in said spaces 24, Whereupon closing the box the same symbols will show through the openings 30, 3| and 32. Then, by slightly rotating each of said knobs, each of said disks or tumblers 22 will be caught under the heads 36 and 31 respectively and the box cannot be unlocked again until the chosen key symbols are brought under said openings 30, 3| and 32. whereupon said tumblers will be released by said heads 36 and 31 and the box may be opened.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come within the purview of the invention claimed may be resorted to, in actual practice, if desired.

box, tumbler engaging means mounted on the wall, one of said locks consisting of a shank having a knob fixed on one end, a retainer disk fixed on the other end, a plurality of disks on the shank, one being a tumbler disk frictionally held but manually rotatable upon the shank, one of said disks being a symbol dial, said lid having bores through which certain of the symbols are exposed, said dial-disk having identical correlative symbols on each side thereof, said tumbler having a peripheral gap adapted to pass over said tumbler engaging means and through which one at a time of said symbols may be exposed, said dial and tumbler being of a common diameter. 2. The combination of a series of permutation locks mounted on a box lid, each of said locks being alike in construction, a Wall within the box, tumbler engaging means mounted on the Wall, one of said locks consisting of a shank having a knob fixed on one end, a retainer disk fixed on the other end, a plurality of disks on the shank, one being a tumbler disk frictionally held but manually rotatable upon the shank, one of said disks being a symbol dial, said lid having bores through which certain of the symbols are exposed, said dial-disk having identical correlative symbols on each side thereof, said tumbler having a peripheral gap adapted to pass over said tumbler engaging means and through which one at a time of said symbols may be exposed.

3. The combination of a series of permutation locks mounted on a box lid, each of said locks being alike in construction, a wall within the box, tumbler engaging means mounted on the Wall, one of said locks consisting of a shank having a knob xed on one end, a retainer disk xed on the other end, a plurality of disks on the shank, one being a tumbler disk frictionally held but manually rotatable upon the shank, one of said disks being a symbol dial, said lid having bores through which certain of the symbols are exposed, said dial-disk having identical correlative symbols on each side thereof.

4. The combination of a series of permutation locks mounted on a box lid, each of said locks being alike in construction, a Wall Within the box, tumbler engaging means mounted on the Wall, one of said locks consisting of a shank having a knob xed on one end, a retainer disk xed on the other end, a plurality of disks on the shank, one being a tumbler disk frictionally held but manually rotatable upon the shank, one of said disks being a symbol dial, said lid having bores through which certain of the symbols are exposed.

5. The combination of a series of permutation locks mounted on a box lid, each of said locks being alike in construction, a wall within the box, tumbler engaging means mounted on the Wall, one of said locks consisting of a shank having a knob ixed on one end, a retainer disk fixed on the other end, a plurality of disks on the shank, one being a tumbler disk frictionally held but manually rotatable upon the shank.
